摘　　要：选用木荷、青冈、红叶石楠3个树种,分别采用芽苗移栽、种子直播、扦插进行网袋容器苗与裸根苗的对比育苗试验。结果表明:网袋容器育苗法能有效控制1年生木荷和青冈苗的主根生长,促进须根生长。与浅根性的树种木荷相比,深根性树种青冈经网袋容器育苗后,根质量及其总生物量的比例显著降低,表明网袋容器对青冈的修根作用比较明显。还观察了3个树种的苗木生长规律,并提出了相应的网袋容器育苗技术措施。A comparative trial on net container seedling and bare root seedling with seedling transplanting,direct-seeding and cutting for three tree species including Schima superba,Cyclobalanopsis glauca and Photinia serrulata were conducted.The results showed that net container seedling could effectively control main root growth and promote lateral root growth of annual S.superba and C.glauca.Significant decreases appeared in the weight of root and it＇s proportion with the total biomass in shallow-rooted tree species S.superba,compared to deep-rooted tree C.glauca by the net container seedling.It was shown that net container seedling had a obvious role of root relief for C.glauca.This research also described the growth pattern of the seedlings of three tree species and proposed the corresponding measures of net container nursery cultural techniques.
